好写了几个DEMO方法主要是get 和post 至此服务端大功告成由于和anroid通信数据最主要是json
打开eclipse

程序代码：

Runnable runnable = new Runnable() {
        @Override
        public void run() {

            // 该部分是传参并更新控件
            Message msg = new Message();
            msg.what = -1;
            // 发送消息到Handler
            CommonData app = (CommonData)getApplication();
            HttpPost request = new HttpPost(app.getLoginaddress());// wcf地址
            request.setHeader("Accept", "application/json");
            request.setHeader("Content-type", "application/json");

            // 构造json
            JSONStringer vehicle;
            try {
                // Message为方法参数名字
                vehicle = new JSONStringer().object().key("user").object().key("UserName")
                        .value(edittext_user_username.getText().toString().trim()).key("PassWord")
                        .value(edittext_user_pwd.getText().toString().trim()).endObject()
                        .endObject();
                // 向WCF服务发送请求
                StringEntity entity = new StringEntity(vehicle.toString(), "UTF-8");
                request.setEntity(entity);//

                HttpResponse response = httpClient.execute(request);
                if (response.getStatusLine().getStatusCode() != 200) {

                    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity()
                            .getContent()));
                    String line = "";

                    while ((line = rd.readLine()) != null) {
                        Integer integer = Integer.valueOf(line.replaceAll("\\D+", "")
                                .replaceAll("\r", "").replaceAll("\n", "").trim());
                        if (integer > 0) {
                            //保存登录用户ID

                            Log.d("****passworderror****", "passworderror");
                        }
                    }
                }




            } catch (Exception e) {

涉及到了java代码了其实和c#语法是类似的
主要代码块都已经注释了和c#引用rest服务如出一辙

程序代码：

HttpClient client = new DefaultHttpClient();
                HttpGet request = new HttpGet(app.getMenuaddress() + "/" + app.getUserid());

                HttpResponse response = client.execute(request);
                HttpEntity responseEntity = response.getEntity();
                char[] mbuffer = new char[(int)responseEntity.getContentLength()];
                InputStream stream = responseEntity.getContent();
                InputStreamReader reader = new InputStreamReader(stream);
                reader.read(mbuffer);
                stream.close();

                JSONArray plates = new JSONArray(new String(mbuffer));
                String[] groups = new String[plates.length()];
                for (int i = 0; i < plates.length(); i++) {
                    JSONObject temp = (JSONObject)plates.get(i);
                    String value = temp.getString("Value");

                    map.put(temp.getString("Value"),temp.getString("Trainid"));
                    //mapotid
                    mapotid.put(temp.getString("Value"),temp.getString("Otid"));

                    groups[i] = String.valueOf(value);
                }

请求实体类的数据主要代码如下

至此 android成功请求wcf json数据测下下效率还不错
